I just bought my house in Jan. The Previous owner had sealed the entrance in the basement with a few 2X4s and plywood to an entrance from the outside, The Bilco doors are locked and I have no way of seeing the condition of the entrance. I would like to tear the the whole entrance out and seal it. But thinking later I may want to add a bedroom down stairs. It is quite drafty in the winter. Any thoughts or ideas as to how I may keep the cellar doors in place and seal it so it is not so drafty. Or should I rip it all out and seal it all up and eliminate the entrance.
